​Sounds

Sound is another form of data that is stored on a computer. Similar to other types of information such as numbers, text and image, the sound is also stored in digital form. But, sound, when produced, is in analogue form, that is, continuous varying data. To store sound in the computer, it is sampled to obtain thousands of samples per second where each sample corresponds to a binary value.

This GCSE Computer Science module introduces ​​sounds to your students, explaining:

  • What ​is sampling
  • What ​is sampling rate
  • Bit depth
  • Bit rate
